org-export-blocks-preprocess: Marker does not point anywhere

org-export-blocks-preprocess: Marker does not point anywhere

[Matthew Landis]

Hello orgmode fans,

Another issue with org and R giving me headaches tonight.

In the example below, using the :session header argument seems to cause 
problems with export to html.  On export, the *R* buffer is opened up, 
but no file is created.  in the *Messages* buffer, I see

org-export-blocks-preprocess: Marker does not point anywhere

however, if I try to export again, with the *R* buffer already open, 
then things work fine.  This is an OK work around I guess, but I thought 
someone ought to know about it.

Session info:
Windows 7, 64 bit.
Emacs version: GNU Emacs 23.4.1 (i386-mingw-nt6.1.7601) of 2012-02-04 on 
MARVIN
Org mode version 7.8.03
ESS version 5.14
R version 2.14.1

I guess you forgot to include the example?

Example now included! (Thanks Nick, for pointing that out...)

#+begin_src R :session :exports code :results silent

   x <- runif(n = 100, min = 0, max = 20)
   y <- 4*x^2 + 0.3*x + 3 + rnorm(100, sd = 200)

#+end_src

I can't reproduce it either with latest (more or less) or with 7.8.03.
The html export succeeds and the code is exported, pdf export (with
minted) succeeds except that the code block is not processed, because
there is no minted lexer for R (at least in my setup). But I get no
error.

Well, thanks for trying.  In my current work flow, I tend to have an R session 
running before I try to export, so I'm not troubled by this anymore.  I guess 
I'll just wait until it's a problem.
